Privacy Policy
App: Calm Keyboard: Private, No Ads (com.tuanapps.calmkeyboard)
Developer: MQ Co.,Ltd
Last updated: 12 November 2026
This policy applies to the Android app Calm Keyboard: Private, No Ads, package com.tuanapps.calmkeyboard, published on Google Play by MQ Co.,Ltd.
1. Nothing leaves your device
Calm Keyboard has no INTERNET permission. The only permissions it requests are VIBRATE (for haptic feedback) and the Google Play Billing permission (for purchases). Because the app cannot connect to the internet, nothing you type, no suggestion, no clipboard entry and no setting is ever sent to us or to anyone else. We do not collect, store on a server, share or sell any data.
2. What is stored on your device
Words the keyboard has learned (for suggestions), your clipboard history, your snippets, your theme and keyboard settings are stored locally on your phone. You can delete them at any time: use Forget learned words and the clear options for the clipboard history and snippets in the app. Uninstalling the app deletes all of it.
3. Password fields and incognito typing
Text typed in password fields is never learned and never recorded in the clipboard history or anywhere else. Incognito typing, when switched on, stops the keyboard from learning anything while it is active.
4. No ads, no analytics
The app shows no advertising and contains no analytics, tracking or crash-reporting SDK. It does not use the advertising ID.
5. Purchases
Calm Plus, Calm Studio and Calm Founder are one-time purchases handled by Google Play. We receive no payment details; the app only uses Google Play's confirmation to unlock the features. Google's own privacy policy applies to the purchase.
6. How to delete your data
Clear learned words, clipboard history and snippets inside the app, or uninstall the app. There is no account and no server-side data, so there is nothing else to delete.
7. Children
The app is not directed at children under 13 and does not collect personal data from anyone.
8. Contact
Questions or requests: use the developer contact on the Google Play listing of Calm Keyboard: Private, No Ads.
